BALlNG-PRESS.'

C-JPECIPICATION forming part of Letters Patent No. 365,187, dated June21, 1887.

Serial No. 232,500.

(No model.)

To all whom, it may concern.-

Be it known that I, \VILLIAM A. LAIDLAW, a citizen of the United States,residing at Cherokee, in the county of Crawford and State of Kansas,have invented certain new and useful Improvements in Billing-Presses, ofwhich the following is a specification, reference being had to theaccompanying drawings, in which- Figure 1 is a perspective view showinga baling-press with my improvements attached, the feed-opening being onthe side. Fig. 2 is a plan of the same. Fig. 3 is a side elevation ofthe same on the feed side. Fig. 4 is a horizontal sectional view of aportion of the press through the baling-chamber and feed-chamber. Fig. 5is a similar view, but showing charges of hay in the baling and feedchambers and the relative positions of the follower and thefeed-compressor. Fig. 6 is a plan view of a modification, part of thebaling-chamber being broken away. Fig. 7 is a side elevation of same.

The object of my invention is to provide a compressor for compressingthe hay to onehalf of its bulk before delivering it into thebale-chamber, thereby dispensing with the usual door and catchesnecessary thereto.

The invention will be first described, and then particularly pointed outin the claims.

In the drawings, Figs. 1 to 5, inclusive, I have shown my improvementsapplied to a press for which Letters Patent of the United States No.347,811 were granted to me on the 24th dayof August, 1886. I have shownonly so much of the press as will be necessary to a clear understandingof my improvements.

A represents the frame of the machine suitably braced by cross-pieces,and having a feedopening in one side adjacent to the balingchamber.

B represents the feed-chamber at the side of the frame in front of thefeed-opening, the said chamber being about twice the length of thefeed-opening. The feed-chamber B is formed of an end piece, I), at rightangles to the rear end of the feed-opening, and top and bottom pieces,bb, between which the'fed-compressor 0 slides. The compressor 0 issecured at its inner end to a vertical bar, 0, working in the opening abetween the chamber B and the side of the frame A, and connected at itsouter corners to a sliding frame, D, working under parallel guide-bars EE, secured at their ends to cross-pieces E E on the top and bottom ofthe frame A. The cross-pieces E E are also connected by the long rods EE", extending along the inner adjacent sides of the guidebars E andsecured in place by nuts. The transverse bars (I d of the frames D areeach provided with a cleat, d extending across the guidebars E E, andfriction-rollers d are journaled between the bars (I dand their cleats(1 with their peripheries engaging the inner faces of the guide-rods E,so as to hold the frame perfectly steady and lessen friction. To thecleats d, or other part of the sliding frame, one or more springs, F,are secured, which spring or springs is or are connected to the mainframe A, so that the sliding frame D and its compressor (J will bereturned to their normal positions. The cross-bars d of frame D projectbeyond the sides of the main frame and are connected by vertical strips(2, provided with buffers or contact-pieces The outer edge of thecompressor O is connected with the ends of the front vertical bar, (i bymeans of the crossed brace d ,to strengthen the compressor at that pointagainst the strain exerted upon it. The balingchamber is made wider infront of its feed-opening, as shown at A so that when the compressor 0has compressed a charge, as shown in Fig. 5, and the same has beenpushed into the bale-chamber,the follower J may the more readily movethe same toward the delivery end away from the feed-opening. Thecompressor 0 is inclined, as shown best in Figs. 2, 4, and 5, so thatthe feed-chamber will be widest at its end adjacent to thefeed-opening,and thereby allow the compressed charge to be more readilypushed into the baling' chamber. It will be noticed that any loose hayprojecting from the charge in the 0113.111 ber across the forward sideof the feed-opening will be folded down by the next, compressed chargeentering the bailing-chamber, as shown in Fig. 5.

XVhen the sweep L is in the position shown in Fig. 2,and a charge is inthe feed-chamber B, the sweep is first moved in the direction shown bythe arrow 1, Fig. 2, to operate the compressor 0. After the charge hasbeen compressed it is pushed by the operator into the baling-ehamber,andthe sweep is moved. in

I GO

the direction of the arrow 2, and strikes the block m and turns the camM, which,acting J, which returns the follower,will cause the saidfriction-wheel to press on the inclined rim of the cam and complete itsrevolution, whereby the opposite blockmt, will be thrown against theopposite side of the sweep, so that the sweep can operate the cam byreversing its movement. The rearward movement .of the sweep at bothsides of the frame A is limited by the stops 1?.

The same hay-retainers O and their springs O are used as in said priorpatent; but I. also place one in the top and one in the bottom, as wellas in the sides of the baliug-chamber,.so as to hold the front side ofthe charge.

It is obvious that instead of having the rollers on the frame D slidingbetween the guiderods E the longitudinal bars of the frame mightslidebetween guide-rollers, which would be the mere reversal of the presentconstruction. By compressing the charges before delivering them to thebale-chamber'the h'ay will not bulge out when the follower or plunger isretracted,as do charges of loose hay.

In Figs. 6 and 7 my improvements are shown applied to the machine forwhichLetters Patent No. 359,081 were granted to me March, 8, 1887. ber Bare at the top of the press instead of the side. The sliding frame D isoperated by the sweep in the same manner as in the side feed, and thecompressor 0 is connected to-the frame D by means of the twolongitudinal The feed-opening and chain-s widened in front of itsfeed-opening in advance o of the retracted position of the follower,with the'feed-chamber adjacent to the feed-opening, and thelongitudinally sliding compressor working in said feed-chamber, andinclined from its inner end outward toward the closed end of the saidchamber, substantially as set forth.

2. The combination, with the main frame having a feed-opening in itsbaling-chamber, a follower, and the sweep for operating the same, of afeed-chamber at the feed-opening, a compressor working Within the saidchain ber, and a sliding frame connected to said compressoraudextendinginto the path of the sweep at opposite sides of the main frame,substan- 65 tiall y as set forth.

3. The combination, with the mainframe. th'e baling-chamberhaving afeed-opening, and the follower, of a feed-chamber adjacent to thefeed-opening, and being provided with an opening between the inner sideof the chamber and the frame, a compressor within said feed-chamber,guidebars on top and bottom of the main frame, a sliding frame undersaid bars and having a bar to which the compressor is secured working insaid opening, cleats on the sliding frame having anti-friction rollersacting on the inner edge of the guide-bars,

cross-bars at the rear ends of the sliding frame, vertical stripsconnecting the ends of the crosspieces, and the cross brace connectingthe outer edge of the compressor and one of said vertical strips, andthe sweep adapted to strike said vertical strips, substantially as setforth.

4. -In a baling-press, the combination, with the main frame, thefollower, a retractingspring therefor, the heart-shaped cam havingopposite blocks, and the sweep mounted on the axis of the cam betweenthe blocks, of the feed chamber, the compressorin the feedchamber, andthe sliding frame connected to the compressor and operated by the sweepin its rearward movement, substantially as set forth.
